Description

Technical Field

[0001] The present invention relates to a monitoring device, and in particular to a real-time monitoring device for building inclination applied in the technical field of building monitoring. Background Art

[0002] During the service life of a building, building materials undergo long-term aging, resulting in a decline in their performance. Due to factors such as irrational use and demolition and modification of load-bearing components, the building's integrity is poor and the structure is loose. Affected by geology and the environment, its installation center of gravity gradually tilts, and local parts of the building tilt to the side. In severe cases, it may topple over and over. It is necessary to conduct long-term monitoring, inspection and tracking of the tilt and deformation of dangerous and old buildings.

[0003] Chinese patent CN114322934A discloses a "Building Tilt Warning Device for Building Monitoring." By providing a second laser and a photosensitive plate, the device measures the offset distance of the second laser's light on the photosensitive plate and the vertical distance between the second laser and the photosensitive plate. This facilitates measurement of the building's tilt at various angles, quickly providing a tilt rate indicator to personnel. Chinese patent CN217951809U discloses a "Building Tilt Monitoring Device." By incorporating a shock-absorbing component into the device, the device's rubber shock-absorbing pads initially reduce vibrations caused by external loads such as construction. Furthermore, the spring shock absorbers further reduce vibrations caused by external loads such as construction. Furthermore, after vibrations are caused by external loads such as construction, the buffer blocks, buffer grooves, and mating blocks work together to further reduce deviations in the monitoring device's monitoring results. This effectively improves the device's shock-absorbing effect during actual use, effectively reducing the impact of vibrations caused by external loads such as construction on monitoring accuracy.

[0004] During the monitoring process of a building, the building may vibrate due to construction reasons. The external force vibration generated by the construction can easily affect the accuracy of the monitoring device. In addition, since most existing monitoring devices use gravity vertical method for longitudinal calibration, after the monitoring device is affected by the vibration, its own monitoring structure requires a long time to recalibrate. Since it cannot quickly restore its own monitoring capability, the collected monitoring data is in a state of violent fluctuation, affecting the accuracy of the monitoring data. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the monitoring structure requires a long time to be recalibrated and cannot quickly restore its own monitoring capability, thereby affecting the accuracy of the monitoring data.

[0006] To solve the above problems, the present invention provides a real-time monitoring device for building inclination, comprising a device sphere, a monitoring liquid capsule placed at the bottom of the device sphere, a monitoring plate covering the top of the monitoring liquid capsule, a pressure detection module distributed in an annular pattern fixedly connected to the top of the device sphere, a probe fixedly connected to the detection end of the pressure detection module, and the bottom end of the probe abuttingly connected to the monitoring plate;

[0007] A buffer bubble is fixedly connected between the pressure detection module and the monitoring board, the bottom end of the probe is fixedly connected to the bottom end of the buffer bubble, the middle part of the device sphere is fixedly connected to a fluid bin, a connecting tube is fixedly connected between the fluid bin and the buffer bubble, and the fluid bin and the buffer bubble are both filled with non-Newtonian fluid, a closing cover is fixedly connected to the top of the fluid bin, a threaded shaft is rotatably connected to the middle part of the closing cover, a pressure plug is threadedly connected to the outer surface of the threaded shaft, and the pressure plug is slidably connected to the inner wall of the fluid bin.

[0008] In the above-mentioned real-time monitoring device for building inclination, the inclination and fluctuation state of the monitoring liquid bag is affected by the lifting and lowering of the probe, and then the pressure detection module is used to detect the pressure data to reflect the building inclination data. When the building vibrates, the buffer bubble is used in combination with the non-Newtonian fluid filled inside to perform vibration buffering, effectively avoiding the monitoring liquid bag from experiencing violent fluctuations, facilitating the restoration of normal operation of the monitoring device, and effectively avoiding violent fluctuations in the monitoring data.

[0009] As a further improvement of the present application, a center contact is fixedly connected to the bottom of the fluid bin, and a resistance groove is provided in the middle of the monitoring plate. The center contact and the resistance groove resist each other, so that the monitoring plate fluctuates with the center contact as the fulcrum, thereby effectively reflecting the tilt state of the building.

[0010] As a further improvement of the present application, the device sphere is divided into an upper shell and a lower shell, and the upper shell and the lower shell are fixedly connected by bolts, which facilitates the disassembly of the device sphere and thus facilitates the maintenance and replacement of the monitoring device.

[0011] As a further improvement of the present application, the bottom end of the lower shell is fixedly connected to a bottom fixing plate, and the top end of the lower shell is fixedly connected to a side fixing plate. The bottom fixing plate and the side fixing plate correspond vertically to each other. Through the bottom fixing plate and the side fixing plate, the monitoring device can adapt to different buildings to be tested, thereby effectively improving the adaptability of the monitoring device.

[0012] As another improvement of the present application, a layered cover is fixedly connected to the bottom of the fluid bin, and a ring-shaped connecting hole is provided on the surface of the layered cover. The connecting holes correspond to the connecting tubes, and a separator is fixedly connected between the lower openings of two adjacent connecting holes. The bottom space of the fluid bin is separated by the layered cover, and the separator prevents the influence between the two adjacent connecting holes, thereby realizing that the connecting holes correspond to the connecting tubes.

[0013] As another improved supplement of the present application, the internal movable connection of the connecting hole is provided with a shielding plug, and a limiting flow hole is opened in the middle of the shielding plug to limit the flow of the fluid passing through the connecting hole through the limiting hole, thereby effectively preventing a large amount of fluid from passing directly through the connecting hole.

[0014] As another improved supplement to the present application, the top of the shielding plug is fixedly connected to a fixed rod, the top of the fixed rod is fixedly connected to the pressure plug, and the fixed rod is used to realize the linkage between the shielding plug and the pressure plug. When the pressure plug drops, the shielding plug releases the restriction on the connecting hole and restores the ability of the connecting hole to flow with a large flow rate.

[0015] As another improved supplement to the present application, the bottom edge of the shielding plug is fixedly connected to a limiting ring, the outer diameter of the limiting ring is larger than the inner diameter of the connecting hole, and the limiting ring limits the upward movement of the shielding plug, so that the shielding plug can only be separated from the connecting hole through a downward movement.

[0016] To sum up, the present invention affects the lifting and lowering of the probe by monitoring the tilt and fluctuation state of the liquid bag, so that the pressure detection module generates pressure changes, and the pressure data obtained by the pressure detection module reflects the tilt data of the building. When the building vibrates, since there is a buffer bubble between the pressure detection module and the monitoring plate, and the buffer bubble is filled with non-Newtonian fluid, the buffer bubble is used in combination with the internally filled non-Newtonian fluid to perform vibration buffering, that is, the instantaneous solid response of the non-Newtonian fluid, which effectively avoids the situation where the monitoring liquid bag fluctuates violently, thereby facilitating the state restoration of the monitoring liquid bag, effectively reducing the recalibration time of the monitoring device, quickly restoring the normal operation of the monitoring device, effectively avoiding violent fluctuations in the monitoring data, and effectively improving the accuracy of data acquisition. By tightening the threaded shaft on the closing cover, the non-Newtonian fluid in the fluid bin is squeezed into the buffer bubble by the pressure plug, and the buffer bubble is over-expanded, so that the buffer bubble limits the fluctuation ability of the monitoring liquid bag and the lifting ability of the probe, and the state of the monitoring device is static, which is convenient for the transportation and storage of the monitoring device.

[0029] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0030] The first implementation method:

[0031] Figures 1 to 3FIG1 is a diagram showing a real-time monitoring device for a building inclination, comprising a device sphere 1, a monitoring liquid capsule 101 being placed at the bottom of the device sphere 1, the monitoring liquid capsule 101 being made of a silicon capsule, the top of the monitoring liquid capsule 101 being covered with a monitoring plate 102, a pressure detection module 103 distributed in an annular shape being fixedly connected to the top of the device sphere 1, a probe 104 being fixedly connected to the detection end of the pressure detection module 103, a piezoelectric sensor being contained inside the pressure detection module 103, when the probe 104 moves upward, the pressure data obtained by the pressure detection module 103 becomes larger, and when the probe 104 moves downward, the pressure data obtained by the pressure detection module 103 becomes smaller, thereby realizing that the pressure data corresponds to the inclination data, the bottom end of the probe 104 is in contact with the monitoring plate 102, and the pressure detection module 103 is connected to the monitoring plate 102. A buffer bubble 2 is fixedly connected between the monitoring plates 102, the bottom end of the probe 104 is fixedly connected to the bottom end of the buffer bubble 2, a center contact 105 is fixedly connected to the bottom of the fluid bin 201, and a conflict groove 106 is provided in the middle of the monitoring plate 102. The center contact 105 conflicts with the conflict groove 106, so that the monitoring plate 102 fluctuates with the center contact 105 as a fulcrum, thereby effectively reflecting the tilt state of the building. A fluid bin 201 is fixedly connected to the middle of the device sphere 1, and a connecting pipe 202 is fixedly connected between the fluid bin 201 and the buffer bubble 2. Both the fluid bin 201 and the buffer bubble 2 are filled with a non-Newtonian fluid. The non-Newtonian fluid used in this embodiment is a polyethylene glycol suspension. Those skilled in the art can also select other non-Newtonian fluids according to technical requirements.

[0032] When using the monitoring device, due to the influence of the building's tilt, the monitoring liquid capsule 101 inside the device sphere 1 produces tilt fluctuations, which in turn affects the rise and fall of the probe 104, and then causes the pressure detection module 103 to produce pressure changes, so that the pressure data obtained by the pressure detection module 103 reflects the building's tilt data. When the building vibrates, since there is a buffer bubble 2 between the pressure detection module 103 and the monitoring plate 102, and the buffer bubble 2 is filled with non-Newtonian fluid, the buffer bubble 2 is used in conjunction with the internally filled non-Newtonian fluid to perform vibration buffering, that is, the instantaneous solid response of the non-Newtonian fluid, which effectively avoids the monitoring liquid capsule 101 from experiencing violent fluctuations, thereby facilitating the state restoration of the monitoring liquid capsule 101, effectively reducing the recalibration time of the monitoring device, quickly restoring the normal operation of the monitoring device, effectively avoiding violent fluctuations in the monitoring data, and effectively improving the accuracy of data acquisition.

[0033] Figures 4 and 5As shown, a closing cover 203 is fixedly connected to the top of the fluid bin 201, a threaded shaft 204 is rotatably connected to the middle of the closing cover 203, a pressure plug 205 is threadedly connected to the outer surface of the threaded shaft 204, and the pressure plug 205 is slidably connected to the inner wall of the fluid bin 201. The device sphere 1 is divided into an upper shell 107 and a lower shell 108, and the upper shell 107 and the lower shell 108 are fixedly connected by bolts, which is convenient for disassembly of the device sphere 1, thereby facilitating the maintenance and replacement of the monitoring device. The bottom end of the lower shell 108 is fixedly connected to a bottom fixing piece 109, and one end of the top of the lower shell 108 is fixedly connected to a side fixing piece 110, and the bottom fixing piece 109 corresponds vertically to the side fixing piece 110. The bottom fixing piece 109 and the side fixing piece 110 are used to enable the monitoring device to adapt to different buildings to be tested, thereby effectively improving the adaptability of the monitoring device.

[0034] When transporting and storing the monitoring device, tighten the threaded shaft 204 on the closing cover 203 to drive the pressure plug 205 downward to squeeze the non-Newtonian fluid in the fluid chamber 201 into the buffer bubble 2, causing the buffer bubble 2 to over-expand. The over-expanded buffer bubble 2 is stably positioned between the pressure detection module 103 and the monitoring plate 102, thereby enabling the buffer bubble 2 to limit the fluctuation ability of the monitoring liquid capsule 101 and the lifting ability of the probe 104, thereby achieving a stationary state of the monitoring device and facilitating transportation and storage of the monitoring device.

[0035] When repairing the monitoring device, the device sphere 1 is disassembled into the upper shell 107 and the lower shell 108 to expose the internal structure of the device sphere 1. Then, the pressure detection module 103 and the monitoring liquid capsule 101 are replaced. The fluid in the fluid chamber 201 is replaced by opening the sealing cover 203 on the top of the fluid chamber 201.

[0036] When installing and fixing the monitoring device, the monitoring device is placed on the surface of the building. When it is fixed to the building through the bottom fixing piece 109, the horizontal tilt of the building can be detected. When it is fixed to the building through the side fixing piece 110, the vertical tilt of the building can be detected.

[0037] Second implementation method:

[0038] Compared with the first embodiment, a layered cover 3 is added, and the fillers in the fluid compartment 201 and the buffer bubble 2 are changed to traditional Newtonian fluids. Silicone oil filling is recommended. Those skilled in the art can also choose other Newtonian fluids according to technical requirements. The specific new structures are as follows, and the remaining structures are consistent with the first embodiment.

[0039] Figures 6 to 10As shown, the bottom of the fluid bin 201 is fixedly connected with a layered cover 3, and the surface of the layered cover 3 is provided with communicating holes 301 distributed in an annular manner. The communicating holes 301 correspond to the communicating tubes 202, and a separator 302 is fixedly connected between the lower openings of two adjacent communicating holes 301. The bottom space of the fluid bin 201 is separated by the layered cover 3. The separator 302 prevents the influence between the two adjacent communicating holes 301, so that the communicating hole 301 corresponds to the communicating tube 202. The interior of the communicating hole 301 is movably connected with a shielding plug 303, and a limiting flow hole 304 is provided in the middle of the shielding plug 303. The flow rate of the Newtonian fluid passing through the communicating hole 301 is limited by the limiting flow hole 304, which effectively avoids a large amount of Newtonian fluid from flowing through the communicating hole 301. The fluid directly passes through the connecting hole 301. The top of the shielding plug 303 is fixedly connected to a fixing rod 305. The top of the fixing rod 305 is fixedly connected to the pressure plug 205. The fixing rod 305 is used to realize the linkage between the shielding plug 303 and the pressure plug 205. When the pressure plug 205 descends, the shielding plug 303 releases the restriction on the connecting hole 301, restoring the high flow capacity of the connecting hole 301. The bottom edge of the shielding plug 303 is fixedly connected to a limiting ring 306. The outer diameter of the limiting ring 306 is larger than the inner diameter of the connecting hole 301. The limiting ring 306 restricts the upward movement of the shielding plug 303, so that the shielding plug 303 can only be separated from the connecting hole 301 by descending movement.

[0040] When the building vibrates, the Newtonian fluid filled in the buffer bubble 2 is squeezed out by the fluctuation of the monitoring liquid capsule 101, and the squeezed fluid enters the fluid compartment 201 through the connecting tube 202. Since the bottom of the fluid compartment 201 is layered by the layered cover 3, and the corresponding connecting hole 301 of each connecting tube 202 is separated and divided by the partition plate 302, the squeezed Newtonian fluid needs to pass through the connecting hole 301. However, there is a blocking plug 303 in the connecting hole 301, and the blocking plug 303 only has a small-diameter blocking plug 303 for circulation. Therefore, the Newtonian fluid in the buffer bubble 2 cannot be squeezed out in a short time, and the same Newtonian fluid cannot enter the buffer bubble 2 in a short time. Therefore, the buffer bubble 2 has the same vibration buffering ability as in the first embodiment, effectively avoiding the situation where the monitoring liquid capsule 101 fluctuates violently, thereby facilitating the state restoration of the monitoring liquid capsule 101, quickly restoring the normal operation of the monitoring device, and effectively avoiding violent fluctuations in the monitoring data.

[0041] When transporting and storing the monitoring device, tighten the threaded shaft 204 on the closing cover 203 to drive the pressure plug 205 to descend and squeeze the Newtonian fluid in the fluid compartment 201 into the buffer bubble 2. While the pressure plug 205 descends, the fixed rod 305 is used to synchronously drive the shielding plug 303 to disengage the shielding plug 303, thereby restoring the flow capacity of the connecting hole 301, so that the Newtonian fluid in the fluid compartment 201 can quickly enter the buffer bubble 2, causing the buffer bubble 2 to over-expand, and achieving the same static state effect of the monitoring device as the first embodiment, which is convenient for transportation and storage of the monitoring device.

[0042] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
